WASHINGTON (AP) -- Convicted D.C. sniper Lee Boyd Malvo says in a newspaper interview that seeing the reaction of a victim's husband made him feel like "scum."

Malvo expresses remorse in an interview with The Washington Post published Sunday. Tuesday marks the 10th anniversary of the beginning of the deadly spree in the Washington area carried by Malvo and John Allen Muhammad. The pair has been linked to 27 shootings across the country, including 10 fatal attacks in the Washington area.

Malvo tells the Post that the devastated reaction from victim Linda Franklin's husband stands out in his memory of the rampage. Franklin was killed outside a Home Depot in northern Virginia.

Describing how he felt when he saw the man's face right after the shooting, Malvo says: "You feel like the worst piece of scum on the planet."

Post reporter Josh White interviewed Malva who said: "I was a monster. If you look up the definition, that's what a monster is. I was a ghoul. I was a thief. I stole people's lives. I did someone else's bidding just because they said so. ... There is no rhyme or reason or sense."

Malvo told the Post reporter that there is no way to apologize to the victims family.

"I am sorry. I am sorry...there's no way to express that. I mean, what am I going to tell them? I'm sorry I murdered your own child. I'm sorry I killed your husband. I'm sorry I murdered your wife. What do I tell the child who is waiting for his father to come home? And dad never showed up..."

He also spoke about what they would do when on a shooting rampage.

"We drive up, I park, he'd park, we go in the trunk, I put my window down half way and I can see whatever is in front of me, to my left and to my right. My focus is on witnesses, passengers, and...I tell him to shoot..and it was just one rapid one after another..."
